My Tank Thread
Hmmm...one possible solution I could imagine would be to determine how much water will be pulled daily from the system (could be done by measuring waste water) and then having a peristaltic pump replace that much water from a saltwater reservoir. I wouldn't think this would be necessary on most systems, but perhaps if someone is running a small nano or a pico or not doing water changes, this could be necessary.My interest is in the water removal. If all three tests use 15ml of water, it's safe to say that is 5ml per test. At 4 Alkalinity tests and 2 Calcium & Mag tests per day; that's 40ml of water total per day. Assuming you do weekly water changes (Some of us dont), that is a little over 1.1 cups of water removed. With an auto-top off system in place, this would dilute your specific gravity over a period of time since the 1.1 cups are being replaced with RODI water. For the control freaks, I would think we would need a salt water feed to dump salt water in as replacements (Especially for those that dont do water changes). Maybe im overthinking it and the swings could be minute (Especially on a much larger water volume system).
